Information sensitivity

Information sensitivity is the control of access to information or knowledge that might result in loss of an advantage or level of security if disclosed to others.

Loss, misuse, modification, or unauthorized access to sensitive information can adversely affect the privacy or welfare of an individual, trade secrets of a business or even the security and international relations of a nation depending on the level of sensitivity and nature of the information.

Non-sensitive information

Public information

This refers to information that is already a matter of public record or knowledge. With regard to government and private organizations, access to or release of such information may be requested by any member of the public, and there are often formal processes laid out for how to do so. The accessibility of government-held public records is an important part of government transparency, accountability to its citizens, and the values of democracy.Public records may furthermore refer to information about identifiable individuals that is not considered confidential, including but not limited to: census records, criminal records, sex offender registry files, and voter registration.

Sensitivity (control systems)

The controller parameters are typically matched to the process characteristics and since the process may change, it is important that the controller parameters are chosen in such a way that the closed loop system is not sensitive to variations in process dynamics. One way to characterize sensitivity is through the nominal sensitivity peak :

where and denote the plant and controller's transfer function in a basic closed loop control System, using unity negative feedback.

The sensitivity function , which appears in the above formula also describes the transfer function from measurement noise to process output, where measurement noise is fed into the system through the feedback and the process output is noisy. Hence, lower values of suggest further attenuation of the measurement noise. The sensitivity function also tells us how the disturbances are influenced by feedback. Disturbances with frequencies such that is less than one are reduced by an amount equal to the distance to the critical point and disturbances with frequencies such that is larger than one are amplified by the feedback.

Sensitivity and specificity

Sensitivity and specificity are statistical measures of the performance of a binary classification test, also known in statistics as classification function:

Thus sensitivity quantifies the avoiding of false negatives, as specificity does for false positives.

For any test, there is usually a trade-off between the measures. For instance, in an airport security setting in which one is testing for potential threats to safety, scanners may be set to trigger on low-risk items like belt buckles and keys (low specificity), in order to reduce the risk of missing objects that do pose a threat to the aircraft and those aboard (high sensitivity). This trade-off can be represented graphically as a receiver operating characteristic curve.
